Thanks for the completed schematics. I have couple of questions for you, if you do not mind commenting on them?
1. What is the significance of non-CMOS vs CMOS 555 (you said to use non-CMOS)?
2. Why is it necessary to opto-couple the Pulse Generator and the Current Amp?
3. Incidentally, what is the tuning for the Pulse Generator (4Hz that Bob Beck and others used) or perhaps fundamental Schumman Resonance?
4. How and where are the electrodes applied (Bob Beck way on the lower arms and blood vessels or elsewhere)? What is the spacing, if elsewhere, and if known what is the impact of the variable spacing between the electrodes?
5. In the Phase Generator why certain channels have a variable pot while others are fixed. Is there a significance of that fixed frequency?
6. Is the combination of the specific frequencies (once set) of each individual channel, and mixed together, of more significance in the final waveform?
7. What are the boundaries of the lowest/highest frequency (all channels) output in the Phase Generator (sorry I did not run this through a circuit sim yet)?
8. Obviously with those variable pots, they would need to be individually tuned for specific application (virus), also referring back to 5. and 6.
9. Because of 8., could the Phase Generator not be substituted with a broad band sweep generator fitting the frequency ranges of each channel?
10. Further to 9., ie. if a micro-controller is used as a sweep generator, each channel could then be more efficient as it would cover entire frequency range at once. What are your thoughts about this?
11. Hypothetically speaking, could the electrodes be replaced with perhaps a piezo ceramic transducer (if the frequency range of the output is not higher than what piezo supports)? I presume the power output would need to be adjusted to sufficiently excites the transducer, but the application would then become contact-less and much easier to handle.
Sorry if this might look like a lot of questions - I do appreciate you answering them.
